So how to plant Kyoho grapes, and what are the planting methods and precautions of Kyoho grapes?
Key points of cultivation techniques of Kyoho grape are serious when it is not cultivated at the right time, so improving the fruit setting rate in cultivation is the key to success.
1, when the diameter of new shoots exceeds 1.5cm, it is not easy to form flower buds and poor fruit setting, so the application of nitrogen fertilizer should be controlled first to prevent the trees from growing excessively;
2. Picking the fruit branches before flowering. Picking should not be too heavy or too light. Too heavy is easy to produce large and small grains, while too light will not improve the fruit setting rate. It is advisable to leave 5 leaves above the ear.
3. Inflorescence shaping, that is, removing 2-4 small branches from the secondary ear and the base of the inflorescence, pinching off the tip of 2-3cm, and leaving only the middle part of 7-8cm, which can make the nutrition supply centralized during flowering, improve the fruit setting rate and make the fruit ear compact;
4, fruit thinning, after fruit setting, appropriate fruit thinning, thinning small grains and fruit grains inside the ear, and leaving 40-50 fruits per ear.
Management technology of Kyoho grape planting 1, timely budding and reasonable pruning.
In the encyclopedia of Kyoho grape planting technology, after the grapes germinate in spring, the double buds and small buds should be erased as soon as possible, and the strong buds should be kept.
Before flowering, the main shoot should be cored for 2 ~ 3 times, and the secondary shoots should be erased in time, so that more nutrients can be transported to the part of the floral organ, and at the same time, some inflorescences should be properly thinned, and1/4 ~1/5 at the end of the inflorescence should be pinched off 3 ~ 5 days before flowering, so that nutrients can be supplied to the remaining fruit particles in a centralized way.
In winter, the medium and long shoots should be pruned, and it is advisable to leave about10 ~15 new shoots per square meter, staggered up and down, so as to ensure that the grape growth per spike reaches15 ~ 25 leaves, and the yield per mu should be controlled within 2500 kg.
In this way, the ear of the fruit can be compact, the fruit grains are neat and mature, and the flavor and color of the berries can be improved.
2. Strengthen fertilizer and water management to prevent premature senescence of trees.
In the encyclopedia of Kyoho grape planting technology, Kyoho grape has strong growth potential and requires high fertilizer and water conditions.
However, irrigation should be appropriate, especially before picking15 ~ 20 days.
It is necessary to control the amount of nitrogen fertilizer and increase the application of phosphorus and potassium fertilizer.
In vineyards that begin to bear a lot of fruits, we should pay attention to increasing fertilizer, keeping the trees strong and extending the period of full fruit.
Water: water the grapes once after they are unearthed in spring.
If the soil is not too dry before flowering, try not to water it
After the flowers wither, the fruit enters a period of rapid expansion, which is a period of high water demand, and can be watered every 10 day.
When the fruit particles begin to color, stop watering to improve the soluble solid content of the fruit.
Before burying the soil in winter, irrigate the grapes with big water once to facilitate the winter.
3. Measures to improve the fruit setting rate of Kyoho grape.
It is a common problem in the production of Kyoho grape to drop flowers and fruits.
The main reasons are the poor development of flower organs, inability to pollinate and fertilize normally, harsh climatic conditions during flowering and malnutrition in trees.
The following technical measures should be taken in production to improve the fruit setting rate of Kyoho grape.
Matters needing attention in Kyoho grape cultivation 1. Flowering, fruit dropping and size and grain.
2. The stability of fruit quality is poor (size, sugar content, color, fruit powder and flavor).
3. Tree vigor, yield and fruiting period (easy to premature senility)
4. Particularity of soil environment, fertilizer and water
5. Pests and diseases (ear stalk brown blight, anthracnose, downy mildew)
Jufeng grape is one of the main varieties in production at present, which has strong adaptability, good disease resistance and cold resistance, and likes fertilizer and water.
Medium-mature tetraploid variety, European and American hybrid, native to Japan.
The above details about how to grow Kyoho grapes, the planting methods and precautions of Kyoho grapes hope to help you!
